Chapter 4 — Troubleshooting and Maintaining the CK3
72 CK3 Mobile Computer User’s Manual
The input device
attached to the CK3
does not work well
or read bar code
labels very quickly.
Set the Scanner Model command to the specific
attached input device. Check enabled bar code
symbologies and enable only the symbologies being
used.
When you release
Scan button, the
Good Read LED
does not turn off.
If the CK3 is configured to use continuous/edge
triggering, the Good Read LED stays on.
If the CK3 is configured to use level triggering, there
may be a problem. Press the Scan button or pull the
trigger again without scanning a bar code label. If the
LED is still on, contact your local Intermec
representative.
The scanner does not
read the bar code
label.
• Aim the scanning beam so that it crosses the entire
bar code label in one pass. Try changing the scan
angle.
• Check the quality of the bar code label, Scan a bar
code label that you know scans well. Compare the
two bar code labels to see if the bar code quality is
too low. You may need to replace the label that you
cannot scan.
• Make sure the bar code symbology is enabled. For
help, see “Configuring the CK3 With Intermec
Settings” on page 27.
• Make sure the application is accepting input by
scanning a bar code. You may need to type this
information instead.
The scanner does not
read the bar code
labels quickly, or the
scanning beam
seems to be faint or
obscured.
The scanner window may be dirty. Clean the window
with a solution of ammonia and water. Wipe dry. Do
not allow abrasive material to touch the window.
The scanned bar
code data that
appears in your
application does not
match the data
encoded in the bar
code label.
The CK3 may have decoded the bar code label in a
different bar code symbology. Try scanning the bar
code label again. Make sure you scan the entire label.
